JOHN G. REHFUSS AND MARTIN O. REHFUSS, OF PHILADELPHIA, PENN- SYLVANIA,ASSIGNORS TO THE BUREAU OAN AND MANUFACTURING COMPANY OF DELAWARE.

SPECIFICATION forming part of Letters Patent No. 754,702, dated March15, 1004. Application filed August I, 1902. Renewed January 4, 1904:.Serial No. 187,741. (No model.)

To c1/,ZZ whom it may concern;

Beit known that we, JOHN G. REHFUss and MARTIN O. RnHrUss, citizens ofthe United States, residing at Philadelphia, in the county of-Philadelphia andv State of Pennsylvania, have invented certain new anduseful Improvements in Apparatus for FluXing Oans; and we do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis'specication.

This invention relates to new and useful improvements in iuxingapparatus for use in connection with can-making machinesyand it consistsin the provision of mechanism whereby the seams of a can may bethoroughly iiuXed while the can is either rotating or movinglongitudinally, in the former case the fluXing apparatus being adaptedto travel with the can as it rotates and when used for luxinglongitudinal seams to remain station-A ratus is -adapted travel with thecans. Fig. 2

is a sectional View through the iuXing-receptacle and parts of theendless carrier` and means for holding and rotating the cans thereon asthey travel in contact with the i'luXing apparatus. Fig. 3 is aperspective view of the iuXing-wheels, showing the relative arrangementof the same whereby the flux is fed from a receptacle by frictionalcontact with the wheels to a can. Fig. 4 is a side elevation of ouriiuXing apparatus shown as held stationary and as applied to a portionof our can-making machine Serial No. 104,870. Fig. 5 is a top plan viewof a modified form of .fluXing-boX.

Reference now being had to the details of the drawings by letter, A Adesignate parallel portions of the frame of our machine for solderingthe tops and bottoms to cans as covered by our application hereinbeforereferred to and to which we have applied our luXing mechanism. Saidframe carries an endless carrier on which the cans B travel in uprightpositions while passing by the two horizontal portions ofthe frame. Inthe drawings, however, vwe have omitted all mechanism for actuating thecans, vas the same forms no part of the present invention. Mounted on ashait OI, journaled in a standard C', forming .a portion of the i'rame,is a lever D, having plication, as they form no part of the presentinvention; but said carriages are shown merely for the purpose ofshowing how the attachments for operating the iiuxing apparatus areoperated. l

- The uxing mechanism comprises one or more receptacles F, which areadapted to contain iiuXing liquid, each of which is supported on abracket-shapedmember F, having preferably dovetailed vconnectiontherewith, as illustrated, and by means of van adjustingscrew F2 saidluXing-recepta'cle may be held .indifferent positions with relation tothe bracket supporting the same. The ends of said bracket-arms aregrooved, as at G and G, and each bracket-arm has a clamping-jaw H, alsoprovided with two concaved portions, which are adapted to form inconnection with the recessed bracket-arms clamping means to receive thegas and air pipes K and K, respectively, said clamping-jaw H being heldto the bracket-arm F by means of bolts L.

Mounted in suitable bearings in the side walls of the receptacle is ashaft N, on which the crank-arms M are pivotally mounted, and journaledin said crank-arms M is a shaft O, on which a beveled linx-feedingfriction-wheel P is mounted, which is in contact with the beveledportion of the wheel Q, which is mounted on the shaft N and ispositioned in the 'luXingreceptacle. Adjustably held in an aperture orsuitable bearing in the shaft O is a stubshaft R, which is held in anadjusted position by means of a set-screw r. Keyed to said stub-shaft Ris a beveled ux-feeding wheel R', which is normally in contact with thebeveled portion of the wheel P. Said crank-arms may be held in inclinedpositions by means of the screws T and T, which are right and leftthreaded and mounted in a similarly-threaded nut T2, whereby as said nutis turned in one direction or the other said screws may be turned out orin for the purpose of holding the arms in adjusted positions. It will beobserved that said crank-arms may be raised or lowered accordingly asthe can to be soldered travels at different elevations, and in eithercase the three wheels of the fluxing mechanism will be in contact withone another, thus insuring a continuous feed of the flux.

Referring to the modified form in Fig. 4, we have shown the uxing deviceheld stationary instead of traveling with the cans which are to havetheir tops and bottoms luXed and soldered, the form shown in saidmodification being for Huxing longitudinal seams of cans which travelunderneath the fluxing mechanism. In this modification two plates M areheld together by means of a pin J, and the flux-feeding wheel Q has adoublebevel circumference instead of a single bevel, as in the otherform of luxing mechanism, and mounted on a shaft O', carried at the endsof said plates M', is another wheel with double bevel (designated byletter R2) which has friction al Contact with a fiuX-feeding wheel P,which has a grooved circumference in which the two wheels Q and R2 havefrictional contact. The wheel P is mounted on stub-shafts P3, which havebearings in the notches in said plates. In the modified form we haveshown a screw T3 passing through a threaded lug on the flux-containingreceptacle and having a head T2 provided for the purpose of raising orlowering said screw when it is desired to adjust the flux-feeding wheelswith relation to the seams which are to be uXed. In Fig.

4 it will be seen that the flux-containing receptacle has dovetailedconnection with the standard Q2 and may be held at any location thereonin order to secure proper adjustment;

In order to impart an accelerated movement to the oscillating lever whentraveling in one direction, we provide a cam W, having a camgroove W2 inthe face thereof, which cam, substantially heart-shaped, is mounted torotate with the shaft C. A lever W' is pivoted at W3 to a standardsupporting the shaft C and carries an antifriction-roller W", which isadapted to travel in said groove W2, and pivotally connecting said leverWV and the oscillating lever is a link W5. By this peculiar constructionof cam and connections with the oscillating lever it will be observedthat the fluxing devices (there being two shown on the upper portion ofthe machine and two on the lower portion for {iuxing the tops andbottoms of cans) will be given a variable reciprocating movement throughthe rod D2, which connects the pivotal pin E with the bracket F, whichis fastened to and is adapted to reciprocate with the pipes K and K',through which pipes air and gas are conveyed to burners for heating thecan, but which are not illustrated, as they do not form any part of thepresent application.

The vmeans for rotating the cans comprises a spring-actuated plate ordisk V, which has a shank portion mounted in one of the links V of thechain of the endless carrier and which shank portion has keyed thereto apinion V2, which is in mesh with the teeth of a gear V3, also carried bya link of the carrier and in mesh with a rack-bar VX. The can is heldbetween said rotary disk and a stationary swiveled disk V4, whichrotates with the disk as it travels with the carrier and during thefiuxing process.

The operation of our improved Huxing apparatus when used in connectionwith the construction illustrated in Fig. 1 of the drawings, in whichthe rotating cans are iuxed, it being understood that the cans aremounted on an endless carrier, only a portion of which, however, isillustrated, as said cans are traveling along the horizontal portions ofthe frame illustrated, the cans are rotated in any suitable'manner, (notillustrated,) and adjacent to the path of the rotating cans are locatedthe fluXing devices, and as the linx-feeding wheel R comes in contactwith a can adjacent to its connection with the top of the can, which inthe upper portion of the carrier is inverted, said wheel R will be heldyieldingly against the can, as illustrated in the detail View, and therotary movement of the can will impart by frictional contact with saidwheel R a movement to the latter, and ux will be fed from the receptacleby the bevel-wheel Q to the wheel P and thence to the wheel R', onto theseam to be soldered. As a can comes into contact with the lower bevelededge of the wheel R the latter will be raised slightly. In case thereshould be a little variation in the location of the plane in which theseam to IOO IOS

be soldered is positioned the wheel R and the wheels in contacttherewith will rise or lower and still be in operative connection withone another. As the cans are traveling in the direction indicated .bythe arrow, the fluxing will be accomplished while the iiuxingwheels arebeing driven forward by means of link connection with the oscillatinglever D, said lever being driven by means of the heartshaped cam W,which is keyed'to rotate with the shaft C, said lever having pivotallink connections with a lever VV, carrying an antifriction-rollerjournaled in a groove in said cam. By reason of the peculiar shape ofsaid heart-shaped cam it will be observed that an accelerated movementis given to said oscillating lever when not moving in the direction ofthe carrier, and having a slower movement while iiuxing a can than onthe return movement of the oscillating lever, which carries the uxingdevices back to come in contact with the following two cans. It willthusbe seen that the tops of two cans are fluxed simultaneously on theupper portion of the machine and the bottoms of two cans are iiuXedsimultaneously with the tops on the lower .portion of the frame, itbeing understood that said oscillating lever actuates two sets offluX-ing apparatus of similar construction, but reversely arranged, one setbeing to iiuX the tops of the cans, while the other is provided forfiuxing the bottoms of the cans.

In the modification our iiuxing apparatus is positioned so that thewheel PJl will travel over or rest upon the longitudinal seam of the canas the same is fed forward on a former after having been turned intocylindrical form and after its edges are interlocked and clenched bymechanism which forms no part Vof the present'invention.l
